DRAG-SAW.

SPECIFICATION forming part of Letters Patent No. 338,005, dated March 16, 1886 Application filed June 19, 1885. Serial No. 169,238.

To all whom it may concern.-

Be it known that we, IRA B. WARREN and CHARLES M. POTTER, of Waucoina, in the county of Fayette and State of Iowa, have invented a new and Improved \Vood-Sawing Machine, of which the following is a full,clear, and exact description.

The object of our invention is to provide a new and improved power-machine for sawing pieces and logs of wood into blocks of the desired length.

The invention consists in the peculiar construction and arrangement of parts, all as hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of our improved sawing-machine. Fig. 2 is a side view of the same.

On one end of a base-frame, A, standards B are secured, in which two bars, 0, are journaled-one above the other-and to each bar 0 a bar, D, is secured, in the free ends of which asaw-blade, E, is held. The bars D are united by a rod, F, and a screw-rod, F, on which a nut, G, is screwed, by means of which the sawblade can be tightened. By drawing the nut G up tight, the bars D are drawn together at the rod F and from each other at the blade E.

On standards H, a shaft, I, is journaled, on which are mounted a pulley, J, on one end and afiy-wheel, K, on the other end. A belt, L, passes over the pulley J and over a pulley, M, on a shaft, N, on which is also mounted a pulley, 0, over which a belt, P, passes,which is also passed over apulley, Q, on the drivingshaft R, on which a pulley, S, for the drivingbelt, is mounted. The standards H are braced by rods H from the standards B. The shaft N is provided with a crank, U, connected by a rod, V, with the top bar D. The beam or log \V is placed in a trough, Y, secured on bars X, pivoted on the base-frame A. The saw-frame bars D pass between guide-bars a, braced by bars b.

(No model.)

The operation is as follows: The shaft N is revolved from the main shaft R, and the fly v wheel shaft I is revolved from the shaft N. The bars D are worked up and down between the guides at by the connecting-bar U, cansing the blade E to cut into the log WV on the supportingframe X Y. The log W is pressed toward the saw-blade until the blade has cut entirely through the log,when the frame is swung from the saw and the log shifted, and so on.

Having thus fully described our invention. we claim as new and desire to secure by Letters Patent 1. In a sawingmachine, the combination, with the base A and standards B, of the bars (J, journaled one above the other in the said standards, the saw-carrying bars D, secured to the bars 0 and connected together by the rods F F, the rod F being provided with the nut G, the shaft N, journaled in the base and provided with the crank U and pulley O, the rod V, connected to said crank and to the upper bar D, the shaft R, provided with the pulleysQS, and the belt P, substantially as shown and described.

2. In a sawing-machine, the combination, with the base A, the standards B H, the bars 0, journaled in the standards B, one above the other, the bars D, secured to the bars 0. and the saw E, secured between the free ends of the bars D, of the shaft N, journaled in the base below the free ends of the bars D, and provided with the crank U and the pulleys M O, the rod V, connected to the crank and to the upper bar D, the shaft I, journaled in the upper ends of the standards H and provided with the pulley J and fly-wheel K, the shaft R, journaled in the base and providedwith the pulleys Q S, and the belts L P, substantially as herein shown and described.
